Title: Electron crystal or positive-hole crystal
Inventor: HIRAYAMA YOSHIO
IPC: H01L21/20
Filed: 1999-04-30
Abstract: PROBLEM TO BE SOLVED: To provide an electron crystal or positive-hole crystal that reduces damage, improves quality and uniformity, allows electrons to be arranged accurately one by one at each dot by accelerating and fixing the formation of the electron crystal or the positive-hole crystal by artificially formed potential modulation. SOLUTION: An ohmic contact electrode 16 is formed from the upper portion of a wafer, and a positive voltage is applied between the ohmic contact electrode and a back gate electrode 17, thus accumulating electrons that have lost the freedom of movement being confined in a vertical direction on a hetero interface layer. Since the hetero structure is non-doped, a two-dimensional electron 15 with high mobility can be formed in the wafer, and electron density can be freely controlled by a back gate voltage. A circular dot 19 is left so that it forms a triangular lattice at a period of 70 nm between ohmic electrodes 16a and 16b on the surface of the wafer, and fine machining for etching so that the periphery can be made shallow is made by electron beam exposure, thus forming weak potential modulation with a period of 70 nm on the hetero interface.

Title: Vertical magnetic recording medium
Inventor: TSUTSUMI KAZUHIKO
IPC: G11B5/667
Filed: 1984-06-13
Abstract: PURPOSE:To decrease the thickness of a titled medium by forming an iron nitride film as a soft magnetic film on a base body and forming a CoCr alloy film on the iron nitride film. CONSTITUTION:Pure iron as a target is reactively sputtered to form the iron nitride film on the supporting base body. A Cr-Co alloy film is then formed on the iron nitride film by a sputtering method using a Cr-Co alloy as a target by which a vertical magnetic recording medium having a comosite structure is obtd. The medium is thus constituted into the small thickness and therefore film curling is decreased in the case of, for example, a tape and good runnability is obtd. The medium is made more inexpensive as well.

Title: Current differential protecting relay unit
Inventor: SHUDO ITSUO
IPC: H02H3/28
Filed: 1991-05-29
Abstract: PURPOSE:To suppress influence of maintenance on other terminals and to simplify the constitution by providing each terminal with means for interrupting transmission signal in both clockwise and counterclockwise directions and further providing means for transmitting the fact that the terminal is halting to other terminals through a transmission circuit. CONSTITUTION:Upon receiving a halt signal, a terminal 4 controls transmission signal interrupting means 105, 205 to interrupt clockwise and counterclockwise transmission signals. Upon interruption of transmission signal, an adjacent terminal which had received a signal from the terminal 4 detects failure of reception signal. In other words, a transmission failure detecting means 103 detects reception failure of clockwise signal whereas a transmission failure detecting means 203 at terminal 3 detects reception failure of counterclockwise signal. The terminal which detected reception failure performs loop back control for detouring the reception failure part. According to the invention, transmitting section can be simplified at each terminal.

Abstract: PURPOSE: To prevent the timer from being newly set even if the data for the timer changes due to mechanical vibrations by controlling the load to be controlled according to the content set in a given area together with the starting of the control by the timer.  
     CONSTITUTION: The outputs of signal generators 20A and 20B, which generate signals corresponding to the displacement amount of a timer control knob, are stored in an RAM in a microprocessor 60 to control a timer. However, when the timer control knob moves due to mechanical vibrations and the like, the outputs of the signal generators 20A and 20B are not newly stored in the RAM in the microprocessor 60. Therefore, the timer is never set against an operator's will.

Abstract: PURPOSE:To obtain efficiently a small mass of a resin uniform in property, by charging a melted resin into a chamber of a container, the chamber being in the shape of a rotating body, and cooling the melted resin while rotating the container about its rotational axis. CONSTITUTION:When a resin that is hard and brittle at normal temperatures such as rosin-modified phenolic resin is taken out from a kettle, the melted resin is charged into the chamber 11 of the container 1 that is in the shape of a rotating body, and the chamber 11 is rotated about the rotational axis 31 to cause the melted resin to adhere to the chamber wall, during which the melted resin cooled and cured. It is preferably that a cooling liquid is forcibly brought in contact with the outer surface of the container 1 and at the same time a cooling gas is fed into the chamber of the container so that the resin is forcibly and rapidly cooled. Thus since the product can be taken out from the kettle quickly and cooled and cured, a uniform product can be obtained.

Abstract: PROBLEM TO BE SOLVED: To easily recognize the installation place of an ID tag and to stably read tag information by an ID tag reader by fitting a responder to an object through an auxiliary member. SOLUTION: The ID tag is fitted to the object through the auxiliary member. For example, the ID tag 20 has a hole 24 bored and is suspended from part of the object or a rod part 30 such as a handrail adjacent to the object by running a wire material (wire, etc.) 40 through the hole 24. When the ID tag reader is carried to read the tag information out of the ID tag, the ID tag 20 needs to be installed nearly within the reach of an inspector on patrol, but the ID tag can properly be installed on the object or any place distant from the object through the auxiliary member, so an operation distance 10 mm to tens of mm can easily be secured. Consequently, the accurate operation of the ID tag reader can easily be guaranteed.
